--json flag doing nothing

[Cedric / ViaDézo1er (viadezo1er)]

bt --version, bt self update --check, bt init and bt switch did not respect --json.

Output after the fix:

bt --version --json
{"version":"0.10.0-canary.8bac725966d7"}

bt init --json
{"initialized":false,"org":"-/","path":"/path/to/repo/.bt/config.json","project":"My Project","status":"already-initialized"}

bt switch --json
✔ Select project · My Project
✔ Save to · Local (bt-output-not-json/.bt)
{"org":"-/","path":"/Users/cedric@braintrustdata.com/repos/bt-output-not-json/.bt/config.json","profile":"-/","project":"My Project","project_id":"e043bad5-7e28-48d9-acf9-bddb05a93394","scope":"local"}

self update outputs different flags depending on whether --check is passed. I think this is fine since the goal of the 2 commands is quite different.

bt self update --json --check
{"channel":"canary","current":"0.10.0-canary.47fd220f51c3","latest":"0.10.0-canary.4a8d89492987","up_to_date":false}

bt self update --json
{"channel":"canary","status":"completed"}

New behavior:
bt --version --json anything-subcommand-flags-whatever acts the same as bt --version --json.
